Das femoroazetabuläre Impingement (FAI) wird durch übermäßigen Knochenwuchs am Acetabulum (Pincer-FAI) oder einen Knochenüberschuss am Femurhals (Cam-FAI) verursacht. Beim FAI handelt es sich meistens um eine Kombination aus Pincer- und Cam-Pathologie, die bei Bewegungen des Hüftgelenks zu einer Einklemmung (Impingement) des Labrums zwischen Pfannenrand und Femurhals führt.

Procedure

Bearbeitung der Cam- oder Pincer-Komponente mit oder ohne Ablösung und Rekonstruktion des azetabulären Labrums. Darunter fällt ggf. auch Abtragung von knöchernen Vorsprüngen bei einer Cam-Komponente.

Capsular Management and Retraction for Cam Resection

Bruce A. Levy, MD, (Rochester, MN) outlines a surgical technique for using the Arthrex® Flexible Arthroscopic Retractor to retract the distal leaflet of capsule after an interportal capsulotomy has been made during a hip arthroscopy procedure. In this cadaveric video, he outlines the retractor insertion steps and demonstrates the increased exposure and visualization of viewing down the distal femoral neck to perform an osteochondroplasty procedure for cam impingement.

BenjaminDomb, MD (Chicago, IL) describes his rationale and surgical techniques foraddressing bony pathology related to femoroacetabular impingement (FAI). Dr. Domb references his preoperative X-raysand multiple fluoroscopic images to demonstrate an arthroscopic surgicaltechnique used to treat the bony morphology associated with FAI.
